PS/2 Mouse Controller with Auto-Ref
EC3592R
FEATURES
‧ 4 wires PS/II interface built-in.
‧ CMOS technology for lower power consumption.
‧ Fully compatible with IBM PS/II series PC.
‧ Supports four working modes: Reset, Stream, Remote and Wrap.
‧ 16 commands plus acknowledgment code.
‧ 7 different sample rates from 10/sec to 200/sec.
‧ 4 different resolutions: 1, 2, 4 and 8 count/mm.
‧ Scaling can be set to 2:1 as specified by IBM spec.
‧ Reduced external component counts by chip integration.
‧ RC oscillation.
‧ Built-in X/Y independent Auto-Ref function (E-CMOS Patented)：X/Y threshold voltage level track
with input signal dynamically and independently.
‧ High standard ESD and EFT immunity.
GENERAL DESCRIPTION
EC3592R is a single chip PS/II Mouse Controller, designed and fabricated in CMOS Technology. The
EC3592R is available in 14-pin or 16-pin P-DIP package.
